"It puts a lot of pressure on the justice system, in terms of magistrates, prosecutors, defence lawyers, but we are pretty proud of what we achieved while we were in Alice Springs."

Superintendent Hollamby says police are now hoping to see a reduction in crime, which typically increases at this time of year in the central Australian town.

"Knowing that just prior to Christmas has not been historically the best time in Alice Springs, with the sheer volume of policing that was done ... hopefully this will go some way to abating what has happened in other years."

Meanwhile, the Central Australian Aboriginal Legal Aid Service says the Alice Springs Jail is too full to deal with people arrested during special police operations in the Red Centre.

Over the past few weeks, nearly a hundred people have been arrested.

Mark O'Reilly from the Central Australian Aboriginal Legal Aid Service says there is nowhere to put them.

He says the Alice Springs Jail is refusing to take prisoners because it is severely overcrowded.

"We think that it is probably as a result of increased police activity in Alice Springs at the moment.

Mr O'Reilly says several Legal Aid clients who are on remand are being kept for up to a week in watch-house cells at the Alice Springs Police Station.

He says these cells do not have showers and are half the size of rooms at the prison.
